Is there a reason you don't use the App Store to update Xcode?

What happens when I try to update Xcode from the App Store:

1. App Store tells me I have to exit Xcode before even downloading the new version
2. I exit Xcode
3. App Store continues to tell me I have to exit Xcode
4. I try restarting
5. Clicking on the update button now makes it claim to be updating, but then 30 seconds later the update apparently fails with no error message
6. Repeat #5 until I give up and download it from the developer portal

Oh, ok. I've had decent luck with using the App Store to get the latest version and downloading old versions as needed.

Because I want to manage what version of Xcode I'm using separate from when I update all the apps through the App Store by hitting one button (or have auto-update turned on).

This is cool. Also I can't believe anyone would use App Store to update Xcode.

I ended up installing El Cp / 7.3 / 9.3 on an older laptop where I don't care how it runs. A quick look at the developer forums and people are complaining about 7.3 issues.

Also, it did take 4 hours.

This is pretty appealing after having Xcode 7.3 stuck at "Installing - 4 minutes" for over an hour in the mac app store. I'm mildly annoyed that all of these awesome tools that are coming out are Ruby-based though. I don't use Ruby for anything, so needing to maintain a Ruby environment just so I can conveniently update Xcode or push up a build kinda sucks.

xgalaxy: Jan 27, 2004; i write code

I've got an interface builder / storyboard problem I need help with.

I've got an NSToolbar in a WindowController. I also have a SplitViewController as the content for the WindowController and that SplitViewController has other ViewControllers showing whatever content. The problem is the NSToolbar content is overlapping the content of the SplitViewController. Eg. it is showing the vertical split through the toolbar and the other parts of the content of the split view are overlapping the toolbar buttons.

I can't seem to find a way to adjust the split views height to accommodate the height of the toolbar.
How do I fix that?

Thanks.

EDIT:
I think I figured it out. I had to uncheck 'full size content view' in the NSWindow properties display. Does this seem like the correct thing to do?

It's news to me that Xcode updates work for anyone. I've had to uninstall and reinstall Xcode to get any updates for almost a year now. App Store updates just sit at "waiting" forever. Maybe I should try that update tool.

edit: Right as I say that, the download started in the App Store after sitting for 15 minutes. It's a Christmas miracle!

Talking directly to APNS is surprisingly annoying, but it's not really all that much code so I wouldn't bother with a third-party push notification service unless that's literally the only thing you need a server for.

I've been on the client side of Urban Airship and Amazon APNS. UA was nice but was getting expensive at our volume, Amazon was cheap but their server library didn't support integrating against the sandbox cert with the same app id that had a production cert (so I was told.. our backend guy's weren't so hot) which seemed dumb as hell.

One nice thing about these services was handling channels and device registrations and keeping track of apple invaliding a device registration.

We'd looked into UA but had heard they were "old news". Now we're currently on our second provider and for some unknown reason, sending a weekly automated push notification at a designated time is too hard and doesn't work properly.

Really, the biggest benefit is it directly links up with our analytics tracking and user profiling. I would LOVE to be able to draw the connections between them all but that would require people's poo poo to actually work :saddowns:

Fun fact, I worked on a pretty major ecommerce app a while ago and we gave qa access to the UA dashboard to test push notifications ahead of black friday. The head qa guy caught a lot of poo poo from us when he send numerous push notifications of "test test" to his 100,000 closest friends.

After that it became company policy that every test push always be some plausible-deniability message like "thanks for downloading $APPNAME! stay tuned for our next update"

# ? Apr 5, 2016 04:18

Should probably have added a caveat that I last used UA like 2 years ago. On a project I'm currently on we plan to use localytics, but that is because thats what the partner wants. I don't know if its going to be a good tool for them or not.

Every iOS SDK seems to be expanding to the point where it can gather analytics, handle push, and gather logs/crash reports. Additional seeing deep/universal links. I wonder how many will be around in a year or two. I guess more business for us when a clients needs us to re-write the whole thing because it was on maintenence mode for a couple years.

Probably a good idea when the keys to the dashboard get handed over. We had similar rules (devs were free to hook up tools to a sandbox cert though)

It's always fun looking at the history of some of these frameworks. You can tell when the original devs move on and it moves into support. Eventually they stop keeping up with new features of iOS and the company disappears. It's unfortunate some of these tools have become industry standard while having the smallest trickle of support. They limp on, at times we shoulder that maintenance and support work.

This WWDC talk explains a use case: https://developer.apple.com/videos/play/wwdc2015/706/?time=2905

I'm imagining, maybe, a stock brokerage app where your requests to the trading API must be signed with the secure element key. Your login process generates a secure enclave key pair and sends the public key up to the backend to persist with the login session.

If the signed request can successfully verify using that public key, you know then that someone authorized had put their finger to the reader.

This is interesting and potentially useful to us (not for what I'm doing right now, protecting a symmetric key), but I haven't been able to export the public key

If understand what he's saying correctly, all keystore items are stored encrypted in the secure enclave, so I don't need to go through the extra step of encrypting a symmetric encryption key with a secure enclave key, I can just store the key in the keystore

Thank you XCUITest for being horribly broken, making our CI User Interface tests useless and unreliable. Without you, QA might have free time on their hands and we all know idle hands are the devil's plaything.

Thank you XCTest for helpfully logging that the app PID died. I appreciate the way you now stop forever causing CI builds to time out without reporting any test failures. We all move too quickly sometimes, but you're helping us slow down to stop and smell the roses.

How do I create an NSNumberFormatter that can accept strings with either plain decimal format or in currency format? Is this even possible?
Basically I want to validate that the input is valid for 'currency'. And I don't care if they put the currency symbols in there or not.
Am I doomed to having to check both formatters for valid input? Why isn't there a good library for this poo poo?

Doc Block: Apr 15, 2003; Fun Shoe

Probably something to do with localization. Currency symbols, thousands separators, and decimal point delineators are all different depending on which country you're in. In some countries, the currency symbol goes in front, in others it goes after the number.

It's annoying, but not that hard to just do the Swift version of

code:

BOOL valid = NO;
NSNumber *currency = [currencyFormatter numberFromString:string];
if(currency == nil) {
    NSNumber *decimal = [decimalFormatter numberFromString:string];
    if(decimal != nil) {
        valid = YES;
    }
} else {
    valid = YES;
}

UIApplication posted:

Dehumanize yourself and face to regex

You could try this, but you'll have to handle different currency symbols somehow unless you very specifically are only accepting values in US dollars.

edit: I could've sworn there was a "requires currency symbol" property for NSNumberFormatter that you could turn off so it'd take "100.0" and "$100.00" but I guess not.

Found it, sort of.

NSNumberFormatter has a lenient property that, when set to YES on a currency style formatter, will allow the user to enter currency without the currency symbol. Be aware that this could potentially allow an invalid number to be accepted as a valid one, though.

Also, while not related to your specific issue, be careful when using floating-point numbers to represent money. Use doubles instead of floats if you really have to use floating-point numbers, etc. etc. etc.
