Telegram iOS app won't build with Xcode 6.1.1

Question

I have downloaded the code source of Telegram app on their website. When I open the project in Xcode 6.1.1, I get the following error:

 UFW (M iphonesimulator): ERROR: Build failed Traceback (most recent call last): File"/Users/yanfeng/Library/Developer/Xcode/DerivedData/Build/Intermediates/MtProtoKit.build/Debug-iphonesimulator/MtProtoKit iOS.build/Script-D05A831218AFB3F9007F1076.sh", line 812, in <module>run_build()File "/Users/yanfeng/Library/Developer/Xcode/DerivedData/Build/Intermediates/MtProtoKit.build/Debug-iphonesimulator/MtProtoKit iOS.build/Script-D05A831218AFB3F9007F1076.sh", line 787, in run_build

Answer 1

MtProtoKit requires https://github.com/kstenerud/iOS-Universal-Framework, so clone it, install "Real Framework", restart Xcode and enjoy!

Answer 2

With Xcode 6, https://github.com/kstenerud/iOS-Universal-Framework is not required for building universal (arm64, armv7, armv7s, and simulator) frameworks for iOS.

You need to remove run script, fix library dependence and Xcode architectures configuration, also confirm architectures of linked binaries.
