+Additional notes
+To change bundleid replace null.null inside the signall.sh script with your custom bundleid.
+Restore to null.null to use bundleid included in the ipa.
+Using a custom bundleid, if the ipa includes additional apps (for example widget and apple watch), the script will automatically change these bundleids using the following convention : custombundleid.extra1, custombundleid.extra2 and so on.
+If you want to change a bundleid for a particular ipa, use only that ipa in the source folder otherwise all ipas present in the source folder will be signed using the same bundleid.
