Start by reproducing the crash at https://app.uniswap.org/#/swap?chain=mainnet on the listed iPhone and Chrome versions, then trace the setItem call in the reported main.4d8e2df0.chunk.js and related chunk. Done means the swap page no longer crashes when the browser quota is exceeded, with a regression test or confirmed reproduction result.
