Building for iOS Simulator, but the linked and embedded framework ‘XX.framework‘ was built for

On-demand resources are predicated on the App Store serving up the initial portion of the application binary and then expecting the application to request the rest manually when it's likely to need it. NSBundleResourceRequest, a key part of the API for managing on demand resources, is new for iOS 9.Which means that applications running on earlier versions of iOS are going to need to given a compatibility behavior--everything gets downloaded--or they're just not going to work at all.

I could not redeem the code from within Safari as it kept taking me to my Top Sites instead of launching the App Store. The only way I found to get around it was use Chrome browser, login to the Developer site and select the download link. This launched the App Store and redeemed the code. However even though my code is redeemed I still have no updates showing in the App Store despite several refreshes.Maybe I just need to be patient although I would like to know why none oif the worked in Safari Version 8.0.7 (10600.7.7)

Ad hoc distribution is the supported mechanism to use if you want to build using an old version of Xcode and load the application onto a device too new for that version of Xcode.There are hackish work arounds involving swapping between Xcode 6 and Xcode 7, but that's likely to cause handshaking problems with the device.

You might be able to downgrade iOS devices, but it is not officially supported. If it don't work they won't help you with that.Same with watches I guess.. I would not try.

If you dig in to the Xcode-beta bundle and find the framework headers, here's how NSArray is now declared:@interface NSArray<__covariant ObjectType> : NSObject <NSCopying, NSMutableCopying, NSSecureCoding, NSFastEnumeration>That <__covariant ObjectType> bit sure looks to me like a user-accessible generic syntax. (Covariant and its opposite, contravariant, have to do with which direction the types should be considered compatible in; for instance, should you be able to pass an NSArray<NSString *> where an NSArray<NSObject *> is expected? Or vice versa? Or neither one?)

This is Beta 1. It will improve in future builds, so try not to worry so much right now.

Considering it is my only device, I can't say i am forced to use iOS 9...but since it is good to test with the latest version, so i am here to report my finding..Historically iOS betas alwasy had poor battery life but never had anything like getting 20% left half day ....wich is surprising considering it is an update tailored at improving battery life...Will i survive? YES Do I understand it is beta? YES ....will it improve? YES an I worried? NO.... but I have to say i am not happy.. now i have to traverl with my battery pack always behind...::(
