Undefined symbols for architecture arm64

[GJDK]

The code which worked 3 months back is throwing the below build error.

Kindly help me in this.

Undefined symbols for architecture arm64:
"_inflate", referenced from:

@moozzyk I resolved this issue by linking libz.tbd file in Xcode.

I am glad you were able to figure this out!

I am having this problem with xcode 11, so, how did you add libz.tbd in xcode?

[moozzyk]

@oswaldozapata - I think you need to go to your project settings and try adding libz.tbd to Linked Frameworks and Libraries. Let me know if this helps.

@oswaldozapata Xcode will fail to build the package without a zlib/libz reference. Depending on how you are using the library, you either need to do as Pawel suggests above, or what I've been doing is adding a import zlib reference at the top of the WebSocket.swift file. That allows Xcode to successfully compile SignalRClient.

import Foundation
#if canImport(zlib)
import zlib
#endif
