Ionic not working on Safari & iOS 11 Using ServiceStack Client

Question

my ionic app not working when calling any webservice (servicestack) method on safari 11.1 (13605.1.33.1.2), see the attched picture also I have the same problem when run to iOS 11 device or simulator.

the app is working on chrome or any android device. My MacOS version 10.13.4 (17E199)

Answer 1

If this issue was from the @servicestack/client then it was caused by Safari 11.1 update that broke W3C's fetch Request API.

A workaround that resolves this issue is available from @servicestack/client v1.0.12.
