App was reviewed by Apple and then published in the app store making it available for everyone to use. However, after it was made available in the app store, we tried to download it to our devices and test to ensure whether the app is working as desired. But, we noticed that the app kept on crashing whenever it was launched. The same app is working fine on Xcode.I am attaching as much information as we could collect at this point of time. Kindly go through the info and revert at earliest.Information:XCODE Version 7.3 (7D175)SWIFT Version 2.2 (swiftlang-703.0.18.1 clang-703.0.29)Device Info: iPhone 5s (Version 9.3.2)Crash Log:Incident Identifier: 567DCDC5-A419-49DD-90FB-EEAF47C26426CrashReporter Key: 083b7e0b680957caa698a19de5826db3d863fcaeHardware Model: iPhone6,2Process: EnglishLearn [230]Path: /private/var/containers/Bundle/Application/70547034-0475-4D3D-9ED2-098D39CDD4B1/EnglishLearn.app/EnglishLearnIdentifier: com.app.englishlearnVersion: 1.1.0 (1.0)Code Type: ARM-64 (Native)Parent Process: launchd [1]Date/Time: 2016-09-12 15:50:17.17 +0530Launch Time: 2016-09-12 15:50:16.16 +0530OS Version: iOS 9.3.2 (13F69)Report Version: 105Exception Type: EXC_BREAKPOINT (SIGTRAP)Exception Codes: 0x0000000000000001, 0x000000010046a5dcTriggered by Thread: 0Filtered syslog:None foundThread 0 name: Dispatch queue: com.apple.main-threadThread 0 Crashed:0 libswiftCore.dylib 0x000000010046a5dc 0x10032c000 + 13040281 EnglishLearn 0x00000001000e020c 0x1000b4000 + 1807482 EnglishLearn 0x0000000100139f08 0x1000b4000 + 5486163 EnglishLearn 0x0000000100136520 0x1000b4000 + 5337924 EnglishLearn 0x0000000100136c94 0x1000b4000 + 5357005 UIKit 0x0000000187eacc40 0x187e98000 + 850566 UIKit 0x0000000187eac844 0x187e98000 + 840367 UIKit 0x0000000188252aec 0x187e98000 + 39103808 UIKit 0x000000018820f5e4 0x187e98000 + 36346609 UIKit 0x000000018820bff4 0x187e98000 + 362085210 UIKit 0x000000018815f0c8 0x187e98000 + 291245611 UIKit 0x000000018816ca80 0x187e98000 + 296819212 CoreFoundation 0x0000000182d04f84 0x182c24000 + 92147613 CoreFoundation 0x0000000182d048bc 0x182c24000 + 91974014 CoreFoundation 0x0000000182d02820 0x182c24000 + 91139215 CoreFoundation 0x0000000182c2cc50 0x182c24000 + 3592016 GraphicsServices 0x0000000184514088 0x184508000 + 4928817 UIKit 0x0000000187f16088 0x187e98000 + 51623218 EnglishLearn 0x0000000100125e9c 0x1000b4000 + 46658819 libdyld.dylib 0x00000001827ca8b8 0x1827c8000 + 10424Thread 1:0 libsystem_kernel.dylib 0x00000001828e8b48 0x1828cc000 + 1175761 libsystem_pthread.dylib 0x00000001829b1530 0x1829b0000 + 54242 libsystem_pthread.dylib 0x00000001829b1020 0x1829b0000 + 4128Thread 2 name: Dispatch queue: com.apple.libdispatch-managerThread 2:0 libsystem_kernel.dylib 0x00000001828e94d8 0x1828cc000 + 1200241 libdispatch.dylib 0x00000001827ac7d8 0x182798000 + 839282 libdispatch.dylib 0x000000018279b648 0x182798000 + 13896Thread 3:0 libsystem_kernel.dylib 0x00000001828e8b48 0x1828cc000 + 1175761 libsystem_pthread.dylib 0x00000001829b1530 0x1829b0000 + 54242 libsystem_pthread.dylib 0x00000001829b1020 0x1829b0000 + 4128Thread 4:0 libsystem_kernel.dylib 0x00000001828e8b48 0x1828cc000 + 1175761 libsystem_pthread.dylib 0x00000001829b1530 0x1829b0000 + 54242 libsystem_pthread.dylib 0x00000001829b1020 0x1829b0000 + 4128Thread 0 crashed with ARM Thread State (64-bit): x0: 0x000000010097ca00 x1: 0x00000001829aa8f4 x2: 0x000000012750e730 x3: 0x0000000000000008 x4: 0x0000000000000000 x5: 0x0000000000000020 x6: 0x0000000000000000 x7: 0x0000000000000fa0 x8: 0x000000010097ca08 x9: 0x0000000000001000 x10: 0x0000000127510000 x11: 0x0000000000000fff x12: 0x000000012750c000 x13: 0x0000000000003fff x14: 0xffffffffffffc000 x15: 0x0000000000003fff x16: 0x0000000182914168 x17: 0x000000010052c040 x18: 0x0000000000000000 x19: 0x00000001a0d103f0 x20: 0x00000001275409e0 x21: 0x00000001888b1cac x22: 0x00000001888b1f1a x23: 0x0000000000000005 x24: 0x0000000000000000 x25: 0x0000000000000001 x26: 0x0000000000000003 x27: 0x0000000000000018 x28: 0x0000000000000000 fp: 0x000000016fd49800 lr: 0x000000010046a5dc sp: 0x000000016fd497f0 pc: 0x000000010046a5dc cpsr: 0x20000000
