SocketRocket Crash

I had multiple crashes

Environment: iOS 9.3 iPhone 5s

This is from Xcode (while debugging):

Assertion failed: (mapped_size >= sizeof(_currentReadMaskOffset) + offset), function __33-[SRWebSocket _readFrameContinue]_block_invoke_2, file 

SRWebSocket.m, line 1131.
warning: could not load any Objective-C class information from the dyld shared cache. This will significantly reduce the quality of type information available.
