build: ios trybot builders failing

[timothy-king]

Trybot builders for ios are failing consistently on https://build.golang.org/.

Example log from https://build.golang.org/log/38129923c6f886f82063cab77355caee3747497a :

ios-arm64-corellium at 1dfb33e8612d20f41cf4e034d9d0838abf75e04b

This looks related to #64751 . Assigning to @dmitshur

Thanks for reporting.

It looks like this builder provides its own bootstrap at /var/root/go-ios-arm64-bootstrap, and its version go1.20.6 is too low for tip. Go tip (1.24 to be) has a minimum bootstrap version requirement of Go 1.22.6 (see https://tip.golang.org/doc/go1.24#bootstrap).

The owners of this builder need to update that location to provide at least go1.22.6 as the bootstrap. @changkun, @steeve (per https://farmer.golang.org/builders), please take a look. Thanks.

Also CC @golang/ios.
