I've been told by one of my fellow developers that new Xcode defaults to adding UI flags to new controls, in this case UILabels, that are incompatible with iOS 6. Yeah, yeah, I know, Apple wants everyone to buy and target the Latest and Greatest�.

This is a dick move. But maybe I'm also a dick because I'm dropping support for iOS 5 / 6 for a little utility app of mine for no other reason than I simply can't test it anymore. I don't have any devices that have iOS 6, and I don't think you can even get an iOS 6 simulator anymore in Xcode 7.

So I'm just going to use 'Apple won't let me' as an excuse in case any users complain.

You can't even get an iOS 7 simulator in Xcode 7. I think you have to go back to Xcode 5 for an iOS 6 sim.

If you have an app in the App Store that works on iOS 6 and then bring out an update that only works for iOS 9, is the iOS 6 version still available to everyone <iOS 9?

I can't run any apps on my device now. "Untrusted Developer. Your device management settings....You can allow using these apps in Settings." There is no Profiles entry under General. It all worked perfectly before, I was able to build and run any project on my device using 9.0 and all the 9.1 Betas. This started with 9.2 beta, although I never had problems before when installing new betas. I've tried deleting all provisioning profiles in Xcode and starting over. I vaguely remember having to sign into the apple developer site on iOS Safari and installing a profile from there, but can't find that anywhere now. WTF?

Yea, it has done that perfectly well in the past, but not anymore with the newest Xcode 7.2 beta. I suppose I have to wait for another Xcode beta release and hope that they fix it before doing any iOS stuff because there seems to be no way around it barring nuking my devices.

Still, it can't be that significant of a portion of the user base to warrant the headache of supporting 5 versions of iOS.

Interface Builder should give you warnings if you do this so you can fix it if the xib/storyboard has its Deployment Target set to earlier than iOS 7 in the inspector. (Or if it's set to get its deployment target from the target itself, and the target or project as a whole has an iOS Deployment Target less than 7.)

If Xcode/IB isn't giving you such a warning that's definitely something to file at bugreport.apple.com with an example.

Our app's build on the App Store still supports iOS 5.1.1. We've been trying to release our new version which bumps that to 7, but have been in preview video limbo for nearly two weeks now.

Has anyone launched an app with preview videos, and if so did you have headaches doing it? We first pushed our app for review at the start of last week, with the videos in the "Processing, may take 24 hours" state - they were edited with Sony Movie Studio but conformed to all the specifications for the H.264 spec listed in the iTunes Connect guide.

After a week we received a Metadata rejection, saying "Your App Previews failed to process during review. Please re-export your previews using QuickTime with the ProRes codec as a .mov file.". Under the "Resources" heading, they linked to the iMovie guide which outputs an mp4 with identical settings to our original file. We responded saying we thought we'd conformed to the requirements, attached a version we'd run through iMovie, and asked for clarification. The reply we got was "In reviewing your reply, it seems your question would be best addressed by iTunes Connect. Submit an inquiry through iTunes Connect Contact Us for an expedited response". We've done this but 3 days later haven't had a reply.

We've tried getting the ProRes codec as they suggested, but it will only install with commercial video editing software (such as Final Cut Pro) installed. Based on the subsequent reply and the mismatch of information in the original rejection, I'm not sure that reviewer is fully clued up on what the problem actually is, so we're not inclined to spend a bunch of money on software we don't need and might not fix the actual problem.

Thinking that there may be some remnants of the previous editing stage causing problems, I tried recording a dummy video straight off an iPad using QuickTime, ran this through iMovie's preview exporter and uploaded to the portal as a test. 24 hours later that version has failed with "Some error".

It feels ridiculous that two weeks on we're still no closer to getting an app review or knowing what the problem is, especially to be held up on a video after five months of engineering effort. It doesn't help that the review team appear to be based on California time zone (or at least work to it) and we're in the UK, so our working hours never overlap.

So I have Xcode 6 and 7 installed side by side on my machine. Using Xcode 7, the app runs fine under all but the iOS 9.x simulators, all of which show our launch xib, and then go to a black screen. I've read that this is possibly some kind of conflict between both Xcode installations sharing simulators... Anyone else see this?

I don't have any of Apple's pro apps installed, yet I have the ProRes codec.

One of my apps has a preview video. It processed pretty quickly. I don't remember if it was h.264 or ProRes. If your video is h.264 codec, are you saving it as .mov or .mp4?

Make sure you're also staying under their maximum bitrate. And only 30fps (

So we tried running our original edited videos through iMovie (which, for the record, generates a h.264 mp4 with no options), exporting them as App Previews and resubmitting for another review. Later in the day we got the same "Some error" message, but then checked iTunes Connect on a different Mac with a slightly newer version of Safari (9.0.1 vs 9.0) and they appear to have processed successfully.. Go back to the Mac with the older Safari (which we were always using before) and it still reports an error. :suicide:

Fingers crossed we'll get through review this time. The videos had sat in the Processing stage for a full week the time we failed, and on subsequent attempts we'd taken the error message as reliable and abandoned early rather than cross referencing with different browsers.

This is off the back of a week spent wrestling with split-screen mode on the iPad for our next update, which seems a nightmare to support if you're doing anything outside the norm of regular UIKit handling. It's all fun, eh?

Anyone know where I might start looking for writing/using remote views in OS X (found while looking through private frameworks)? I notice an NSRemoteView class in OS X headers, but it's obviously undocumented, as it's a private API.

Alternatively, a general approach to creating views or windows the contents of which are managed by external applications.

Built 4 Cuban Linux: Jul 15, 2007; i own america

I have a Swift app and I'm trying to work on some memory problems. It gets killed occasionally due to Jetsam events when its at ~20-30MB (1200-2000 pages) (its an extension).

Anyway, I can't get a consistent reading of memory usage and I have a hard time finding what this 30MB actually corresponds to.

1) When I run attached to the Xcode debugging, Xcode might report something like ~8MB while Instruments activity monitor reports 30.
2) When I run activity monitor and allocations instruments, activity monitor reports 78MB real memory, while allocations reports 46MB transient bytes, and 14MB persistent bytes (which don't even add up to 78MB). I added some memory reporting in my application logs and it reports M: 29.734375 (using this method I found somewhere and converted into Swift):

code:

	class func report_memory() -> String {
		var info = task_basic_info()
		var count = mach_msg_type_number_t(sizeofValue(info))/4
		
		let kerr: kern_return_t = withUnsafeMutablePointer(&info) {
			
			task_info(mach_task_self_,
				task_flavor_t(TASK_BASIC_INFO),
				task_info_t($0),
				&count)
		}
		
		if kerr == KERN_SUCCESS {
			return "M: \(Double(info.resident_size) / 1048576.0)"
		}
		else {
			return "Error with task_info(): " +	(String.fromCString(mach_error_string(kerr)) ?? "unknown error")
		}
	}

basically... how much memory am I actually using? What do I trust when I'm getting multiple reports? If activity monitor reports 70MB and allocations reports 15MB, how do I actually use that to investigate memory usage and improve my app?

Also (with no debugger or instruments attached), my log entry at the beginning of viewDidLoad already reports 17MB used before I do anything. <Warning>: M: 17.78125 | View did load start

My storyboards are all pretty simple with no images. Any hints? I've been able to cut back small amounts here and there, but I can't really tell where most of this memory usage is coming from.

Just about everything you watch / read these days will be out of date simply because of the breakneck pace of Swift evolution. This will eventually slow down, but for now feel free to ask syntax questions here as you run into them.

So far it's not so much syntax/Swift intricacies as it is using Swift in the context of a graphical application. Say, for example, I want to make a tip calculator as practice. I can easily do that as a console application, but I want to make it a single-view iOS app so I can learn about hooking all the buttons, inputs, outputs together. The course I was watching used storyboards to build the interface, but something must have changed in between his version of XCode and mine because if I replicate his steps about half of the things don't work.

I did find the Apple developer library, so hopefully I'll have better success there. I'll certainly come in and ask if I run into any more issues.

Dessert Rose: May 17, 2004; awoken in control of a lucid deep dream...

You can definitely use storyboards with Swift view controllers. You need to tag the instance vars @IBOutlet and the functions @IBAction. Adding those tags will provide a little handle in the gutter of your code editor which you can drag to various corresponding elements in the storyboard.

This worked as of 9.0, anyway, and I don't see it changing anytime soon, it's how IB has worked since it got integrated with Xcode.

CapnAndy: Feb 27, 2004; Some teeth long for ripping, gleaming wet from black dog gums. So you keep your eyes closed at the end. You don't want to see such a mouth up close. before the bite, before its oblivion in the goring of your soft parts, the speckled lips will curl back in a whinny of excitement. You just know it.

So I've got a DialogViewController, and on RefreshRequested, it calls the same function it called to populate itself the first time. However, every time I do it, it gets offset upwards a bit -- the topmost bit gets scrolled above the screen, and even if you drag to it, it bounces right back away, because the app thinks you've gone above where the top should be. And each time you refresh the DialogViewController, a bit more goes off the top of the screen, until you can't even refresh it any more because you can't drag it that far down. The DialogViewController itself contains a Section that is cleared out and then dynamically populated with StylizedStringElements, because I inherited this code and I don't want to tear the whole thing down and rewrite it properly if I don't have to.

I thought this would be a simple fix, but maybe I don't know the right words to describe it, because Google's giving me dick-all. Anyone got ideas? I'll tear it down and replace it with a table if I've got to, but that'll be a hassle.

For us it was dealing with Popovers. UIKit offers basically no help and the docs pretty much say "you might want to fiddle with some buttons or something, good luck".

I wrote an AdaptivePopover extension to UIKit that actually handles popover transitions properly on size class changes. It still can't deal with a modal on top of the popover because UIKit can't handle any view hierarchy changes to view controllers underneath the current view controller. I have a branch that dynamically subclasses UIViewControllers to hook up to the proper lifecycle events that would allow you to defer dealing with popover changes when they are under a modal (after the modal dismisses) but we ended up punting and just dismissing the modal in that scenario. I'm going to try to open source the AdaptivePopover stuff though. It was a real lifesaver.
