Crashlytics reports with Swift methods are hard to read

I recently discovered problems reading Crashlytics reports for crashes in Swift code.
In the picture below you can see what happend to the method names. I've highlighted the interesting information in it:

String+File.swift line 21 $SSo7UIImageC7mymoduleE4load_5blocky10Foundation3URLV_yABSg_s5Error_pSgtctFZ080$S7mymodule23ProfileViewControllerC18loadProfilePictureyy10Foundation3URLVFySo7a6CSg_s5G9_pSgtcfU_AC0ijK0CSgXwz_XxTf1ncn_nTf4ndn_n

It is still usefull but harder to read and understand. Even though, sometimes it doesn't help at all.

I just wonder if there is a way to fix this.
