I would try using the API a bit more instead of HandleCommand. Your original code:

import lldb
debugger = lldb.SBDebugger.Create()
debugger.HandleCommand('platform select remote-ios')
debugger.HandleCommand('process connect connect://localhost:1234')
debugger.HandleCommand('process continue')

New code using the API is a much better way:

import lldb
debugger = lldb.SBDebugger.Create()
filename = None # fill this in if you know the local version of the executable file, else leave as None
triple = 'armv7s-apple-ios' # Modify the ARM architecture to match
platform = 'remote-ios'
error = lldb.SBError()
target = CreateTarget (filename, triple, platform, False, error)
if target.IsValid():
    process = target.ConnectRemote(debugger, "connect://localhost:1234", "gdb-remote", error)
    if process.IsValid():
