Appears to have the same results as Mac. https://bugs.webkit.org/show_bug.cgi?id=214478 It looks like the changes in https://trac.webkit.org/changeset/264492/webkit caused these tests to crash. Adding iOS debug wk2 test expectation, similar to https://trac.webkit.org/changeset/264520/webkit since skipping one causes the next to crash.
