2015-03-31 17:13:59.229 Algorhythm[13646:864917] Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) ( "<NSLayoutConstraint:0x7f9d70c89080 UIImageView:0x7f9d70c6c810.width == 1.10345*UIImageView:0x7f9d70c6c810.height>", "<NSLayoutConstraint:0x7f9d70c60710 UIView:0x7f9d70c99060.width == 2.66667*UIView:0x7f9d70c99060.height + 80>", "<NSLayoutConstraint:0x7f9d70c85fb0 UIImageView:0x7f9d70c6c810.bottom == UIView:0x7f9d70c99060.bottom>", "<NSLayoutConstraint:0x7f9d70c886c0 H:|-(0)-[UIImageView:0x7f9d70c6c810] (Names: '|':UIView:0x7f9d70c65210 )>", "<NSLayoutConstraint:0x7f9d70c88710 H:[UIImageView:0x7f9d70c6c810]-(0)-| (Names: '|':UIView:0x7f9d70c65210 )>", "<NSLayoutConstraint:0x7f9d70c887f0 V:[_UILayoutGuide:0x7f9d70c4d790]-(0)-[UIImageView:0x7f9d70c6c810]>", "<NSLayoutConstraint:0x7f9d70c88840 V:[_UILayoutGuide:0x7f9d70c4d790]-(200)-[UIView:0x7f9d70c99060]>", "<NSLayoutConstraint:0x7f9d70c93e60 H:|-(0)-[UIView:0x7f9d70c99060] (Names: '|':UIView:0x7f9d70c65210 )>", "<NSLayoutConstraint:0x7f9d70c93eb0 H:[UIView:0x7f9d70c99060]-(0)-| (Names: '|':UIView:0x7f9d70c65210 )>", "<NSLayoutConstraint:0x7f9d70cb3eb0 'UIView-Encapsulated-Layout-Width' H:[UIView:0x7f9d70c65210(375)]>" )

Will attempt to recover by breaking constraint <NSLayoutConstraint:0x7f9d70c60710 UIView:0x7f9d70c99060.width == 2.66667*UIView:0x7f9d70c99060.height + 80>

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful. 2015-03-31 17:14:01.085 Algorhythm[13646:864917] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver (<Algorhythm.PlaylistMasterViewController: 0x7f9d70c4f600>) has no segue with identifier 'showPlaylistDetail'' *** First throw call stack: ( 0 CoreFoundation 0x000000010738da75 exceptionPreprocess + 165 1 libobjc.A.dylib 0x0000000108ee5bb7 objc_exception_throw + 45 2 UIKit 0x0000000107d4882b -[UIViewController shouldPerformSegueWithIdentifier:sender:] + 0 3 Algorhythm 0x000000010718a333 TFC10Algorhythm28PlaylistMasterViewController18showPlaylistDetailfS0_FPSs9AnyObject_T + 915 4 Algorhythm 0x000000010718a3b6 TToFC10Algorhythm28PlaylistMasterViewController18showPlaylistDetailfS0_FPSs9AnyObject_T + 54 5 UIKit 0x0000000107fd4c26 UIGestureRecognizerSendActions + 262 6 UIKit 0x0000000107fd38c9 -[UIGestureRecognizer _updateGestureWithEvent:buttonEvent:] + 532 7 UIKit 0x0000000107fd84e6 __UIGestureRecognizerUpdate_block_invoke662 + 51 8 UIKit 0x0000000107fd83e2 _UIGestureRecognizerRemoveObjectsFromArrayAndApplyBlocks + 254 9 UIKit 0x0000000107fce45d _UIGestureRecognizerUpdate + 2796 10 UIKit 0x0000000107c67856 -[UIWindow _sendGesturesForEvent:] + 1041 11 UIKit 0x0000000107c68483 -[UIWindow sendEvent:] + 667 12 UIKit 0x0000000107c34fb1 -[UIApplication sendEvent:] + 246 13 UIKit 0x0000000107c42227 _UIApplicationHandleEventFromQueueEvent + 17700 14 UIKit 0x0000000107c1d23c _UIApplicationHandleEventQueue + 2066 15 CoreFoundation 0x00000001072c2c91 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION + 17 16 CoreFoundation 0x00000001072b8b5d __CFRunLoopDoSources0 + 269 17 CoreFoundation 0x00000001072b8194 __CFRunLoopRun + 868 18 CoreFoundation 0x00000001072b7bc6 CFRunLoopRunSpecific + 470 19 GraphicsServices 0x000000010b496a58 GSEventRunModal + 161 20 UIKit 0x0000000107c20580 UIApplicationMain + 1282 21 Algorhythm 0x000000010719314e top_level_code + 78 22 Algorhythm 0x000000010719318a main + 42 23 libdyld.dylib 0x00000001096c1145 start + 1 ) libc++abi.dylib: terminating with uncaught exception of type NSException (lldb)
