I need help in flattening this array of objects and remove the duplicate SWFIT key for each entry. Current array:

0: {SWIFT: 'GIBAXXXX', PARTICIPANTS: {…}}
1: {SWIFT: 'GIBAXXXX', SETTLEMENT_BANKS: {…}}
2: {SWIFT: 'IQAMXXXX', ISSUERS: {…}}
3: {SWIFT: 'IQAMXXXX', PARTICIPANTS: {…}}
4: {SWIFT: 'IQAMXXXX', SETTLEMENT_BANKS: {…}}
5: {SWIFT: 'CITIXXXX', ISSUERS: {…}}
6: {SWIFT: 'CITIXXXX', PARTICIPANTS: {…}}
7: {SWIFT: 'CITIXXXX', SETTLEMENT_BANKS: {…}}

So a needed result would be something like this:

0: {SWIFT: 'GIBAXXXX', PARTICIPANTS: {…}, SETTLEMENT_BANKS: {…}}
1: {SWIFT: 'IQAMXXXX', ISSUERS: {…}, PARTICIPANTS: {…}, SETTLEMENT_BANKS: {…}}
2: {SWIFT: 'CITIXXXX', ISSUERS: {…}, PARTICIPANTS: {…}, SETTLEMENT_BANKS: {…}}

I tried various ways to reduce this array into an array of objects but I simply could not figure it out.
