ideviceinstaller tools from https://www.libimobiledevice.org/. Use the HEAD versions from
source; the stable versions have bugs that prevents the Go exec wrapper to install and run
apps.

Second, the Go exec wrapper must be told the developer account signing identity, the team
id and a provisioned bundle id to use. They're specified with the environment variables
GOIOS_DEV_ID, GOIOS_TEAM_ID and GOIOS_APP_ID. The detect.go program in this directory will

known to the system compiler (for example, all the GNU C extensions) as
well as the system-specific header locations and system-specific
pre-#defined macros. This is certainly possible to do, but it is an
enormous amount of work.

Cgo takes a different approach. It determines the meaning of C
identifiers not by parsing C code but by feeding carefully constructed
programs into the system C compiler and interpreting the generated

The shift operators shift the left operand by the shift count specified by the
right operand, which must be non-negative. If the shift count is negative at run time,
a <a href="#Run_time_panics">run-time panic</a> occurs.
The shift operators implement arithmetic shifts if the left operand is a signed
integer and logical shifts if it is an unsigned integer.
There is no upper limit on the shift count. Shifts behave
