Swift 2 / iOS 9 - libz.dylib not found

Question

I\'m using some external codes from google in my new Swift 2.0 project that required \"libz.dylib\" in earlier versions. After updating to the new Xcode / the new SDK.

Answer 1

Meanwhile you can use previous SDK. This is my answer for libsqlite3:

Edit: (link content added)

Open terminal, type (change to your desired library, e.g. libz)

locate libsqlite3.dylib

You'll find several files like these:

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/lib/libsqlite3.dylib
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib/libsqlite3.dylib

Go to your project's setting -> Build Phases -> Link with Binaries. Add BOTH files by clicking +, then Add Other. Hit Cmd-Shift-G, and copy-paste the file path. Click Open.

If you install sqlite3 using macports, remove /opt/local/lib from Library Search Path in Build Settings.

Answer 2

You can also add the lybz.dylib from "Other Linker Flags" in the Build Settings by adding the argument -lz.

I had to do this because, using the method where you reference the library from /usr/lib, when I deployed my app to our testers the .dylib library could not resolve and caused the app to crash on launch.
