+# Ivy iOS App source
+
+This directory contains the source code to the Ivy iOS app.
+
+To build, first create the Mobile.xcframework out of the Go
+implementation of Ivy. Run:
+
+```
+go install golang.org/x/mobile/cmd/gomobile@latest
+go install golang.org/x/mobile/cmd/gobind@latest
+```
+
+to install `gomobile` and `gobind`. Then:
+
+```
+mkdir work; cd work
+go mod init work
+go get -d golang.org/x/mobile/bind@latest
+go get -d robpike.io/ivy/mobile
+gomobile bind -target=ios,iossimulator,maccatalyst,macos robpike.io/ivy/mobile robpike.io/ivy/demo
+```
+
+Place the Mobile.xcframework directory in this directory, and
+then open ivy.xcodeproj in Xcode.
+
+You have to specify Development Team for code signing certificate in:
+Project Settings -> Targets -> Signing & Capabilities -> Signing -> Team.
